Is selenium non reactive?
Selenium can be reactive and form compounds with other elements. It reacts with oxygen to form oxides and with water to form various compounds. However, it is less reactive compared to other elements in the same group like sulfur and tellurium.
Which is more metallic oxygen vs selenium?
Selenium is more metallic than oxygen. Oxygen is a non-metal, while selenium is a metalloid that exhibits some properties of metals.
Why selenium is more reactive than sulfur?
Selenium is more reactive than sulfur because it has a lower ionization energy and higher electronegativity, making it more readily form bonds with other elements. Additionally, its larger atomic size allows for easier electron transfer, enhancing its reactivity compared to sulfur.
Which is the most active nonmetal out of argon chlorine potassium or selenium?
Chlorine is the most active nonmetal out of argon, chlorine, potassium, and selenium. It belongs to the halogen group, which is known for its high reactivity. Chlorine readily reacts with other elements to form compounds.
What does selenium and oxygen combined together make?
Selenium dioxide, SeO2
